Does anyone know how to make sure all the fish get food? I know I have to rehome my jd but for now there is no aggression problem. In fact he is the one I am worried about. My yellow lab steels all the food and I never can get him to get any. She will stuff he mouth full to the point where she looks like she might choke. The others do the same. And my jd never seems to get food. For such a tough fish he is so sad! Please help.
